A user equipment (UE) may identify a beam correspondence between a set of synchronization signals transmitted by a base station and an uplink positioning reference signal. The UE may receive a synchronization signal from a base station and determine a transmit beam for the UE to use to transmit the uplink positioning reference signal based on the received synchronization signal and the identified beam correspondence. The UE may then transmit the uplink positioning reference signal using the determined transmit beam. A base station may identify a beam correspondence between a set of synchronization signals and an uplink positioning reference signal, and transmit an indication of the beam correspondence. The base station may then receive the uplink positioning reference signal from a UE based on the transmitted indication of the beam correspondence.

Abstract: A control device includes a cyclic communication part, a message communication part, and a communication management part. The cyclic communication part performs communication according to a preset cyclic period. The message communication part performs communication that need not conform to the cyclic period. The communication management part manages a communication schedule for the cyclic communication part and the message communication part.

When cyclic communication is possible, the communication management part stores the control data in the cyclic communication part, and when cyclic communication is not possible, the communication management part stores the control data in the message communication part.

Abstract: Wi-Fi services multicast to a subnet in a software-defined network (SDN) are extended. An SDN controller centrally monitors a data plane of a Wi-Fi network. Advertisements for services within a first subnet by an advertising station are forwarded to the SDN controller. Parameters of the service of the advertising station are extracted for storage by performing deep packet inspection on the one or more packets. Queries for services within a second subnet by a querying station are also forwarded to the SDN controller. Parameters of the service of the querying station are extracted for storage by performing deep packet inspection on the one or more packets. The query for service to the advertisement matches responsive to the advertisement parameters compared to the query parameters. Responsive to matching, a set of connection parameters necessary for the querying station at the second subnet to connect to the advertising station at the first subnet is sent.
